A Specific Gravity Bottle, also known as a density bottle, is a laboratory glassware used to measure the density or specific gravity of liquids and powders accurately. Here's a description of a Specific Gravity Bottle with a capacity of 100 ml:
Key Features:
1. Material :
- Typically constructed from high-quality borosilicate glass, known for its durability, thermal resistance, and resistance to chemical corrosion.
- The glass material ensures transparency for clear visibility of contents and markings.
2. Design :
- Shape : Generally cylindrical or pear-shaped with a narrow neck and a ground glass stopper.
- Capacity : Holds a precise volume of 100 ml (milliliters), with the volume capacity marked on the body of the bottle for accurate measurements.
3. Ground Glass Stopper :
- Provides an airtight seal to prevent evaporation or leakage of the liquid or powder inside.
- The ground glass stopper ensures a secure closure, crucial for maintaining accurate density measurements.
4. Calibration and Accuracy :
- Designed to be precise and accurate in measuring density or specific gravity, often calibrated to meet strict volumetric standards.
- Suitable for use in scientific research, quality control, and educational laboratories where precise measurements are essential.
5. Usage :
- Density Determination : Utilized in various methods, including the Archimedes principle, to determine the density of liquids and solids.
- Specific Gravity Measurement : Enables the measurement of specific gravity relative to water or other reference substances.
6. Cleaning and Maintenance :
- Requires thorough cleaning before and after each use to remove residues that could affect measurements.
- Handling with care to avoid breakage or damage to the glassware, especially the ground glass stopper.
Advantages:
- Precision : Offers accurate measurements of density and specific gravity due to its precise design and calibration.
- Versatility : Applicable to a wide range of liquids and powders used in scientific, industrial, and educational applications.
- Durability : Made from robust borosilicate glass, ensuring longevity and resistance to chemical exposure.
Applications:
- Laboratory Analysis : Essential in chemistry, physics, and materials science laboratories for conducting density and specific gravity experiments.
- Quality Control : Used in industries such as pharmaceuticals, chemicals, and food processing to ensure product consistency and adherence to specifications.
- Educational Purposes : Valuable in educational settings for teaching principles of density, buoyancy, and specific gravity.
Limitations:
- Fragility : Requires careful handling to prevent breakage, especially when handling the ground glass stopper.
- Cost : Initial investment may be higher compared to disposable plastic density bottles, but offers long-term durability and accuracy.
Conclusion:
A 100 ml Specific Gravity Bottle is a critical tool in laboratory settings for accurately measuring the density and specific gravity of liquids and powders. Its precise design, durable construction, and reliable performance make it indispensable for scientific research, quality assurance, and educational purposes where precise measurements are crucial for accurate analysis and experimentation.
